Bonds are broken by rearrangement of electrons, and then new bonds are made, again by rearrangement (sharing, donating, etc) of electrons.
A chemical substance is a material with a specific chemical compound. A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another. Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.
stoichiometry is very important in chemical equations because it tells you the relationship between substances in the same chemical equation. If you know the properties and relationship of one substance in the equation, you can calculate the relationships between all the substances in the equation.
All chemical reactions occur because of the exchange of electrons between atoms.
When metal is brought into contact with fruit juice, the reaction is that of mild corrosion. This is because of the chemical makeup of both substances.
oxidation is when you lose electrons i have a cool little thing O-oxidation I-is L-losing electrons R-reduction I- is G- gannning electrons OIL RIG

dooodoo
electrons
Both Chemical and nuclear reactions form new substances.
The sharing of electrons via covalent bonds
hi
A chemical reaction occur: the transfer of electrons between elements is involved.

Metals.

The substances in a chemical reaction that are combined are the reactants, and the substances that are formed as a result of the reaction are the products. Reactants are the starting materials, while products are the final end-products. Chemical reactions involve the breaking and forming of chemical bonds between atoms.
